the requirements of the Patented Apr. 30, 1935 2 Claims.

This invention relates broadly to storage batparticularly to motor vehicle batteries and boxes, having as its object-to provide connecting devicesfor the battery terminals for establishing the usual circuit connections with the battery in such a manner that the battery may be slipped from the box and removed from the vehicle without the necessity of detaching any circuit wires.

Further, it is an object of the present invention to. provide for automatically making or breaking the terminal connections without the use of tools and to otherwise eliminate the objections to batteries now in use and that render the removal of the battery diflicult, especially among which is corrosion and the deleterious efiects thereof.

The invention, together with its numerous objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawings wherein is illustrated a preferred embodiment of the invention. g

It is to be understood at the outset that it is in no wise intended to restrict the invention to the precise embodiment herein illustrated and described, other than may be necessary to meet prior art and the scope of the appended claims.

In the drawings:

Figure 1 is a top plan view of an automobile battery and supporting box therefor illustrating my improved terminal connection. v

Figure 2 is-a vertical sectional view through the box with portions of the battery broken away for illustrating certain details of construction being hereinafter more fully referred to.

Figure 3 is a fragmentary endelevational view of the battery and box therefor.

Figure .4 is a side elevational view of a ground contact.

Figure 5 is a plan view of said contact.

Referring to the drawings by reference numerals, it will be seen that 5 indicates generally a portion of a chassis frame bar or other suitable part of an automobile chassis while the reference numeral 6 designates generally a conventional box mounted on the part 5 for receiving the battery designated as awhole by the reference numeral I.

The battery 1 includes amongother parts a container 8 of rubber or other suitable material, and arranged in the container are the battery cells, which cells are three in number and designated by the reference numerals 9, I U, and l I, re-

series in the usual manner by the bars I3.

In accordance with the present invention, instead of having the cells 9 and It provided with the usual type of frusto-conical terminal posts, said cells are respectively provided with terminal posts i4 and I5, respectively and; as shown in the drawings, each of the terminals i l and I5 is of substantially inverted U-shape and strad-- dles an end wall of the container ill in a manner clearly shown in Figure'2.

The outer sides a or legs of the terminals I4 and 55 are provided with flat disk-like heads l6 and IT.

A ground contact with a stud or rivet I8 that is engaged with one side 6a of the box 6 for securing the contact I8 to the inner side of the wall 6a of the box, the free end of the rivet 58' being upset as shown in Figure 1. The contact I8 is so located on the side Ea of the box as to be engaged with the head I6 of the terminal the box 6 as drawings.

The wall 6b of the terminal I 5 has its will be clear .froma study of the box 6 in the region of the upper edge split vertically,

disk is has integral there- It When the battery is slid into the split extending from the upper edge of'the box to a substantially circularopening I9. said wall or side 56b of the ing I9 ,has integral therewith allongitudinally split frusto-conical socket forming flange I9 in which is fitted snugly a substantially frusto-conical contact flange l9 and wall 6a of the box by a suitable sleeve. of insulating material 2i. end of the contact 20 extends inwardly of the box 6 to be engaged by the head I1 of the terminal I5 when the battery is slid into'thebox. The terminal 20 is provided on one end of a cable or circuit wire 22.

The

It vrlllnow be observed that the contacts I8 and 20 on the sides of the box 6 are so disposed to be electrically engaged with the heads I6 and I1 of the terminals 14 and I5 when the battery 1 is slid down into the box 6 to close the circuit through the battery.

The battery boxes now employed on vehicles for holding the battery usually have the sides thereof connected by tie rods, and in the present instance, I have shown the sides to and Bb'of the box 6 member 26 that is insulated from the The largest box about the openconnected by tie rods 23. Thus with this type V of box, a positive connection between the contacts on the walls 611, 6170fthe box and the terminals I4 and I5 up of the nuts provided on one end of the tie will be made upon tightening bolts or rods 23 after the battery has been placed within the box. Also this tightening up of the nuts on the bolts 23 for drawing the sides 6a and 6b of the box inwardly will result in the conical terminal 20 being forced into a Wedging fit within the socket flange l9. Thus a positive-electrical connection will be made, and at the same time provision is made for establishing the usual circuit connections with the battery in such a manher that the battery may be slipped from the box and-removed from the vehicle without the necessity of detaching any circuit wires.

What, is claimed is:

1. A battery carrier receptacle, a fiat disk-like contact on one end wall of said receptacle, and

a'socket on a relatively opposite end wall of the receptaclefa conical contact member having a wedging fit within said socket and a'battery' for disposition within said carrier receptacle provided with terminals positioned for intimate contact with the contacts on the walls of the receptacle upon disposition of the battery within said receptacle.

2. In combination, an electrical battery having a terminal provided with a disk like head lying flat against the outer face of the adjacent end wall of the battery, and a carrier receptacle re- Ceiving said battery, said carrier receptacle having an end wall provided with an integral conical socket and a slit extending downwardly from the upper edge of said end wall to the largest end of the socket and continuing longitudinally of said socket, and a conical contact member fitted within said socket and engageable with the head of the terminal.
